Newport has brought out 5700 High-Power Laser Diode Drivers, available in four different models with various maximum current and compliant voltage levels.
The 5700-30-5 (30A - 5V) and the 5700-80-7 (80A - 7.5V) models are designed for use with single-bar multi-emitter laser diodes.
The 5700-100 (100A - 30V) and 5700-150 (150A-20V) are ideal for stacked multi-bar multi-emitter lasers.
The latter models use a 3000W power supply to provide the highest possible power output to drive the most advanced devices currently used for research in laser development laboratories.
The 5700's features include continuous wave (CW) or pulsed-current mode of operation with the option of either local or remote control.
Full LIV characterisation of laser diodes is attainable via the USB2.0 interface; software drivers are provided with the instrument.
Enhanced safety features protect the laser diode during setup mode by preventing incorrect settings.
When the instrument is powered off, program settings are saved in the non-volatile memory.
Comprehensive laser diode protection is provided through a variety of measures: transient filtering, intermittent contact protection, independent current limit and power limit settings and a slow turn-on sequence.
Users may change setup parameters to facilitate multiple test requirements, making these devices ideal for research and development, manufacturing and quality control.
A single DB25 connector is used for all signal input/output requirements, including the TTL input and output interlock, current monitor and voltage monitor.
A DB25 connector interlock is also included in the instrument.
